How about this? This would require some cover-up make-up for the tattoos (at first). A businesswoman or librarian or schoolgirl (whatever you decide would be most effective) is abducted, stripped by the tentacles, and then the tentacles probe her and begin to cum. As they fill and cover her with more and more cum, she becomes more and more into it. The tattoos start to appear, maybe her hair changes color. She is finally revealed as the Purple Bitch we all know and love. Kind of an origin story maybe. Maybe even a purple lighting effect on the scenery or something as she gets into it.
Just off the top of my head when I saw her on the list of upcoming actors.
